LIQUID-DISPENSING APPARATUS.

Applieation filcd July 25, 1925. Serial No. 46,121.

My invention relatesto improvements in liquid dispensing apparatus ofthe so-called visible type, commonly used for dispensing gasoline. Theapparatus has a Vertically adjustable tube and belongs to that class ofsuch aparatus in which the adjustable tube is on the delivery side ofthe pump in contra-distinction to those having an adjustable overflowtube.

In apparatus of this type the elevated visible measuring container isprovided with a fixed overflow pipe to drain back liquid to the maximummeasuring capacity of the container and the movable discharge pipewhereby any portion of the remaining liquid may be accurately drawn offfor delivery by adjusting the height of the discharge pipe below theopen end of the overflow pipe and thus permitting the discharge of themeasured quantity of liquid.

The principal object of my invention is to provide in such an apparatusmeans for quickly and accurately dispensing the entire number of unitsof liquid which the apparatus is adapted to contain or any lessquantity.

Another object of my invention is to provide a dispensing apparatus inwhich the visible container is set low to facilitate the reading of thequantity graduations onthe container, at the same time having the liquiddelivery outlet from the container high enough to permit the rapid andcomplete draining of the hose into thecontainer ot the customersvehicle. The means employed for accomplishing this is a U-tube and meansfor preventing liquid being siphoned -from this tube on completion ofthe measure for such siphoning would give false measure.

In the particular embodiment of my invention selected for illustrationFigure 1 is a dispensing apparatus of the visible type shown in verticalaxial section certain of the pipes being shown in full line where it isthought that such showing better illustrates the structure, and

Fig. 2 an enlarged cross section on line 2-9031. Fig. 1 as though shownthere in :tull.

Referring now to the drawings, A is the post portion of the casingresting upon the pedestal A and having at its top a cap A the three heldtogether by tie rode a in the usual manner. Upon the pedestal is secureda bracket a in which a quantity stop rod is pivoted and to which a guiderod is secured, as will hereinafter be more fully described.

A glass "container B is secured between the cap A and top plate Z) bytie rods 6 in the usual manner. A hand hole cover 6 facilitates accessto the visible container. The container is provided with the usualquantity graduations as indicated in Fig. 1, the container shown beingof five gallon capacity.

A fill .pipe 0 is connected in the usua manner to any suitable pump (notshown) which draws the supply of gasoline or other liquid from anunderground storage tank (not shown). At its topthe fill pipeC isprovided with a deflector cap 0 which permits quiet filling of thecontainer B to a height above the level of the top of the overflow pipeD, which is lixed in position to rain back excess liquid to the zerograduation on the container B. The overflow pipe D connects with thestorage tank in the usual manner. j

A vent hole 0 is provided in the top of the deflector cap to preventliquid being siphoned out Of the visible container B below the zeropoint upon cessation of pumpmg. i

Into the cap A is threaded. from below one leg E of the U-tube and thedischarge tube Fis adapted to be vertically adjusted withinthe tube Ethrough the stuifling box a to prevent the escape of liquid from thecontainer B around the tube F into the tube E.

At its lower end the tube E is provided with a return bend casting Eforming the base of the U and the other leg E of the U-tube is securedto the member E At the top of the tube E is secured an L e and ahorizontal discharge tube a with any suitable serve valve 6 to controlthe flow of liquid to the customers car.

At a point beyond the serve valve 6 is connected a vent pipe 6'' whichpreferably extends int-o the free space at the top of the container B,and ensures complete and rapid draining of the hose H.

In line with the center of the pipe E through the bottom of the U E isan opening with a stuliing box a through which extends the ustinent rod7 which is secured.

i to the lower end of f of the tube F in any suitable manner, as by forkand rivets as lower end to a crosshead 7 which is raised and lowered .bymeans ofthe rack f pinion f andcrank f A crosshead guide rod f issecured at the bottom to bracket (11, and at the top to a cross plate aand extends through a hole in the crosshead- The height to which thedischarge pipe F is adjustedwfrom time to time is controlled by anysuitable stop mechanism, as that shown by stop rod G pivoted at thebottom in bracket a and at the top in cross plate (L3. It is providedwith a pluralityot individually adjustable stops 9 fixed to the rod G,and the rod is rotated into suitable eon- H tacting'position ofanypredetermined stop g-by meansrof'the bevel g on the shaft 9 I' do notintendt'o' limit myself to the precise structure shown but claim aswithin the gears 9 g and knob scope of my invention'any apparatusreadable on the claims.

Iclaim as my invention and desire to secure by Letters Patent of theUnited States: i j i 1. A liquid dispensing apparatus havingin'combination an elevated measuring contamer for the liquid to bedispensed, a

leg except through said discharge pipe, the other leg of said U-tubeterminating in an outlet pipe, and means connected with said outlet pipefor breaking the siphon from said U-tube.

2. A liquid dispensing apparatus having in combination an elevatedmeasuring container for the liquid to be dispensed, a U-tube whosevertical legs are constantly in fluid communication with each otherbelow said container with one leg connected therewith a discharge pipev'erticall adjustable within said container and Sillt leg of the U-tube,a stuffing box in the bottom of the container through which saiddischarge pipe passes, the other leg of said U-tube tenninating in itserve valve and hose connection, and a vent to facilitate the completeand rapid draining of the hose and thus prevent siphoning liquid fromthe U-tube.

3. A liquid dispensing apparatus having in combination a transparentelevated measuring container for the liquid to be dispensed, a U-tubewhose vertical legs are constantly in fluid communication with eachother below said container with one leg connected with the bottomthereof, a discharge pipe open at both ends to form a liquid passagefromsaid container to said leg of the U-tuhe, an adjusting rod securedto said discharge pipe extending down through a stuffing box in thereturn bend portion of said U-tube, means for adjusting the verticalheight of said discharge pipe by means of said adjusting rod, a stufiingbox in the bottom of said container through which said discharge pipepasses, the other leg of said U-tube terminating in a serve valve andhose connection, and a vent to facilitate the complete and rapiddraining of the hose and thus prevent siphoning liquid from the U-tube.

In testimony whereof I have hereunto set my hand.
